Compositing Difficulty – Pls Help

[Chrys]

Would appreciate assistance to a compositing newbie:

I have the following events –

1. Boy playing piano (Medium shot, top of head up to piano keys)
2. Panning shot of music sheet
3. Gradient from Generated Media

I was hoping to create the following sequence:

Shot starts with boy playing piano. Music Sheet fades in to replace background but the boy, at the extreme left of frame should remain 100% solid with none of the new background (music sheet) spilling over him. Music sheet fades out and background returns.

I have been trying all sorts of combinations and as i am still groping with the parent-child concept, I have not achieved the shot I wanted. I would appreciate some enlightenment with the:

– clip order (or track heirarchy)
– composite modes
– parent child assignments

Thanks a whole lot!

Here’s one way without parent child, and using two tracks.

Top track – boy playing piano.

Bottom Track – Music sheet.

Open Pan Crop on top track, click Mask at the bottom and create a bezier mask around the boy, with feathered edge. If you split this Event where you want to make the change, then turn off the mask for the left hand portion, the edge of one side of the split can dragged over the other to create a fade in the music, and the same later the other way, to fade out the music.

What’s in the background that you are replacing?
